Nanofix Green

Nanofix Green is an Eco-friendly alternative for industrial-grade Formic acid 85% which is commonly used in the leather industry.


Application & Recommendation


  • Nanofix Green (Safe Acid) is suitable for all kinds of leathers wherever Formic

 acid 85% is used. It can replace formic 85% in any formulation.

  • Nanofix Green (Safe Acid) is exothermal just like any other acids commonly used

 in tanneries. When water is added, it increases the temperature of the solution

 during the diluting process.

  • Nanofix Green (Safe Acid) should be diluted with water with a portion of 1:10

 exactly the same as Formic acid. 10% solution can be safely used to

 lower the pH during wetting back (re-chroming).


0.5-1% for wet salted skins or hides.

1-2% for dry salted and dry hides or skins.

  • Non-polluting, eco-friendly and direct replacement for 85% strength Formic acid

 in any formulations. (No need to change the formulation)

  • An additive which imparts more smoothness to the leather surface than formic acid.
  • Unlike formic acid, this product is not corrosive and it’s easy and safe to handle.
  • Smell of acids does not remain in leathers after the final washing step.
  • It produces fewer hydro & Oxy groups thus the leathers will be stronger and darker in

 dye shades after fixation.

  • It accelerates acid penetration in the pickling stage. It leads to tighter, fuller and

 smoother grains in wet-blues after chrome tannage.

  • Lower the BOD & COD content in the effluents than Formic acid.
  • It does not lead to evaporate any smell of fumes during the dilution, because the

 product does not contain Sulphuric, Hydrochloric, or Formic acids.

  • The level of free formaldehyde content as an impurity is significantly lower than

 standard formic acid.
